Strebsteuerung für den Strebausbau mit einer Vielzahl von hydraulisch betätigten Ausbauten (Schilden), die jeweils über ihre Schildsteuerung im Sinne des Raubens, Schreitens und Setzens in Abhängigkeit von der Position der Abbaumaschine (Schräm- oder Hobelmaschine) automatisch umgesetzt werden, wozu die Position der Abbaumaschine automatisch an die Schildsteuerung gemeldet wird.
Kennzeichen:
Die Abbaumaschine ist mit einem Positionsmelder ausgestattet.
Der Positionsmelder besteht aus:
  • 1. einem drehbaren Meßrad (28) mit elektromagnetisch erfaßbaren Umfangsmarkierungen, das die Abbaustrecke abfährt, wie z. B. einem Ritzel
  • 2. zwei induktiven Impulsgebern (Doppel-Impulsgeber 35) durch welche(n) die elektromagnetisch erfaßbaren Umfangsmarkierungen abgetastet werden;
  • 3. einem Mikroprozessor (31), dem die Signale des Doppel-Impulsgebers aufgegeben werden und der die Signale in Positions- und/oder Bewegungsrichtungssignale umsetzt;
  • 4. einem Funkgerät (32) zur Sendung der Positions- und/oder Bewegungsrichtungssignale
ein oder mehrere Funkempfänger (33), die auf der Streblänge verteilt und mit der Schildsteuerung (34) zur Umsetzung der Positions- und/oder Bewegungsrichtungssignale in Signale zum Umsetzen der Schilde (Ausbaueinrichtungen 1-18) verbunden sind.Longwall control for the longwall construction with a variety of hydraulically operated extensions (shields), which are automatically implemented via their shield control in the sense of robbing, striding and setting depending on the position of the mining machine (cutting or planing machine), including the position of the mining machine is automatically reported to the sign control.
Mark:
The mining machine is equipped with a position indicator.
The position detector consists of:
  • 1. a rotatable measuring wheel ( 28 ) with electromagnetically detectable circumferential markings that travels the mining route, such as. B. a pinion
  • 2. two inductive pulse generators (double pulse generators 35 ) by which the electromagnetically detectable circumferential markings are scanned;
  • 3. a microprocessor ( 31 ) to which the signals of the double pulse generator are applied and which converts the signals into position and / or direction signals;
  • 4. a radio ( 32 ) for transmitting the position and / or direction signals
one or more radio receivers ( 33 ) distributed over the face length and connected to the shield control ( 34 ) for converting the position and / or direction of movement signals into signals for converting the shields (expansion devices 1-18 ).
